[...]these systems have limitation in terms of detection area. [...]this project proposes a new solution to directly track the human subject movement and subsequently increase the efficiency of the air conditioner system. 2.Research Method The objective of the project is to develop an intelligent decoy tracking system based on vision application to detect human presence for spot cooling. [...]the air will be directed according to the command given by microcontroller. 2.1.Acquisition of Target Human Position This system involves Kinect sensor which is used to detect human presence. The average respond time of the system is less than 1 second. [...]the system can be considered to have fast response which is sufficient for this application. 3.7.Precision of the System Desired angle was calculated using normal tangent rule as shown in Equation 2. Angle of movement for Blade Y was limited by it mechanical structure. Besides the result of Blade Y in Area C, the others are considered good as the difference between desired angle and moved angle was small. 4.Conclusion Vision based human decoy system is a system that able to track user once the target steps into the detection area and spot the target human.
